nextElem()

- (V2TIMElem *) nextElem

Get the next Elem. If your message has multiple Elems, you can get the next Elem object from the current Elem. If the return value is nil, it means the Elem acquisition is over. For detailed usage, please refer to the document Message sending and receiving

appendElem:()

- (void) appendElem:

(V2TIMElem *)

elem

Add the next element
To configure multiple elements, after creating a Message object, you can add the next element via the element object of Message. The following is the sample code for creating V2TIMTextElem and V2TIMCustomElem:

    V2TIMMessage *msg = [[V2TIMManager sharedInstance] createTextMessage:"text"];
    V2TIMCustomElem *customElem = [[V2TIMCustomElem alloc] init];
    customElem.data = ["自定义消息" dataUsingEncoding:NSUTF8StringEncoding];
    [msg.textElem appendElem:customElem];

Attention

• This API can be called only by elements of a Message object created via createMessage.
• This API can be used to add V2TIMTextElem, V2TIMCustomElem, V2TIMFaceElem, or V2TIMLocationElem.
